Mounting and connecting an antenna wire in a transponder

Abstract

During mounting to an inlay substrate, at least one end portion (including end) of an antenna wire is positioned directly over a terminal of the chip module for subsequent connecting thereto. A sonotrode is disclosed with a cutter above the capillary for nicking the wire. The antenna may comprise two separate stubs, each having an end portion (including end) positioned over a terminal of the chip module. Additional techniques for mounting the antenna wire are disclosed.

What is claimed is: 
     
       1. A method of mounting a wire to an inlay substrate for a transponder comprising a substrate, a chip module and an antenna wire disposed on the substrate, said chip module comprising two terminals, the method comprising:
 during mounting the wire, ensuring that at least one end portion including an end of the wire is positioned directly over a corresponding at least one terminal of the chip module for subsequent connecting thereto without requiring repositioning; 
 wherein: 
 the antenna wire comprises two lengths, or “stubs” of wire; 
 a first of the two stubs of antenna wire is formed by first embedding on the substrate, then causing a first unembedded end portion of the antenna wire to be located directly over a corresponding first one of the two terminals of the chip module; 
 a second of the two stubs of antenna wire is formed by first embedding on the substrate, then causing a second unembedded end portion of the antenna wire to be located directly over a corresponding second one of the two terminals of the chip module. 
 
     
     
       2. The method of  claim 1 , further comprising
 connecting the two distal ends of the two stubs of antenna wire together. 
 
     
     
       3. The method of  claim 2 , further comprising
 connecting the two distal ends of the two stubs of antenna wire together at a capacitor. 
 
     
     
       4. The method of  claim 1 , wherein:
 the stubs are of unequal length. 
 
     
     
       5. The method of  claim 1 , further comprising
 subsequently connecting the two unembedded end portions of the antenna wire stubs to the corresponding two terminals of the chip module.
